4d2e0fffb0 FreeBSD 11.0 lacks ELFCOMPRESS_ZLIB 
FreeBSD 11.0 unfortunately lacks ELF compression definitions in their
elf.h (sys/elf_common.h), and 11.1 introduced them.
b9167d33a1

Though we can add workaround, we simply drop support because
FreeBSD 11.0 is already EOL at November 30, 2017.

0528838b37 addr2line.c: no need to keep fd around after mmap 
POSIX mmap(3) manpage stipulates mmap bumps the reference
count of the file description.  Thus keeping a file descriptor
to maintain the reference is not necessary.

If this didn't work, every extension .so would require a
permanent FD, which is obviously not the case.
